SPF identifies which mail servers are authorized to send emails for a domain. With SPF, if a receiving server checks an SPF record successfully, the sending server is authenticated. If SPF doesn’t check out, it’s forwarded as spam.
In order to specify Benchmark as an authorized email sending source for your domain, you need to add an SPF record for Benchmark.
Adding an SPF Record for Benchmark
Login to your DNS management console
Navigate to Tools & Settings > DNS Template
You need to edit the DNS TXT record related to SPF
An SPF TXT record for Benchmark will have the following syntax:
yourdomain.com TXT v=spf1 include:bmsend.com -all
Publish this record in your DNS records section for your respective domain.
Note: If you don’t have an SPF record previously for your domain, simply publish the above-mentioned record to enable SPF for outgoing emails using Benchmark. If you do have an existing SPF record in your DNS, you need to modify it to include Benchmark, as shown below:
Previous SPF record: v=spf1 include:spf.zoho.com -all
Modified SPF record: v=spf1 include:spf.zoho.com include:bmsend.com -all
Wait for 72 hours to allow your DNS to process the changes
